Bearing design

 
 

Axial deep groove ball bearings are available as:

 
   
 

Basic bearing design

Non-self-retaining, easy-to-fit bearing units

 

Axial deep groove ball bearings are part of the group of axial ball bearings. The bearings are of a multi-piece construction and, due to their design, are not self-retaining. As a result, it is possible to mount the bearing parts (shaft locating washer, housing
See Mounting dimenstions
locating washer, ball and cage
The part of a rolling bearing which separates, retains and, where necessary, guides the rolling elements
assembly, support washer) separately from each other. In order to guide the balls, the shaft and housing

raceways) with a defined osculation, in which the rolling elements circulate. The ball set is retained by a sheet steel cage

or a solid brass cage ➤ Table 2. When using these bearings, the designer does not need to produce the bearing parts for his bearing arrangement

and match these to each other himself, but can instead use a standarised, ready-to-fit unit.

 
 

Single direction axial deep groove ball bearings

These axial deep groove ball bearings comprise a shaft locating washer, a housing

Load carrying capacity

 
imageref_17757187211_All.gif   Axial deep groove ball bearings are suitable for the support of predominantly axial loads. They must not be subjected to predominantly radial loads.  

Single direction bearings

 

Single direction axial deep groove ball bearings can support axial forces in one direction and support the shaft on one side ➤ Figure 2.

 

Double direction bearings

 

Double direction axial deep groove ball bearings support axial forces in both directions and can guide the shaft on both sides ➤ Figure 3.

 
 

Compensation of angular misalignments

 
imageref_17757187211_All.gif   Axial deep groove ball bearings react with high sensitivity to angular misalignments. In cases where the contact face for the housing

can be compensated by means of bearings with a spherical housing

Under axial load, the balls are guided under favourable rolling conditions at the base of the groove. This deteriorates, however, if the centrifugal force occurring at higher speeds and very low loads presses the balls outwards. In this case, detrimental sliding motions can occur between the rolling elements and the raceways due to centrifugal forces and gyroscopic moments. In order to prevent these sliding motions, the bearings must be subjected to the minimum axial load Fa min ➤ Equation 4. This can also be achieved by means of preloading, for example using springs.
